Use of Petri nets in assembly definition

Assembly tasks are one of the principal activities found in manufacturing. It is specified in different ways, for instance as an exploded view drawing.

We propose the use of Petri nets, in an interactive way, as a task level graphical language to express the qualitative aspects of the assembly.<
